Treat home studying like dieting
Something that has helped me when I have to study is essentially KNOWING I will be distracted, so what I do is schedule said distractions. I block out X amount of time for work/study for the day. Say 3-4 hours. In that 3 to 4 hour block I set myself 30 mins to do w/e that has nothing to do with my studying/work. Generally having structure will help due to if your mind knows you have all day you will invariably go off on tangents and side projects all day and rationalize Oh but I still have time etc. I will legit set an alarm/timer for those 30 mins. The next step is your own self control on following that. Also, unless your cellphone is being used to help study, put it on silent/vibrate. Human brain hears the phone go off and were trained to instantly look at it. Turn off alerts for a bit. Hope this helps.
